Tesla cars are known for their advanced technology and features, but sometimes they may encounter some glitches or bugs that affect their performance.
One of the common problems reported by some Tesla owners is the turn signal no sound issue, where the car does not make any sound when the turn signal is activated.
This can be annoying and potentially dangerous, as it may confuse other drivers or pedestrians on the road.
There are several possible causes and solutions for this problem, and this article will provide some troubleshooting tips based on the information available online.
However, this is not a comprehensive or definitive guide, and you should always contact Tesla support or visit a service center if the problem persists or worsens.
Why Causes Tesla Turn Signal No Sound?
#1. System fault
Sometimes, the car’s software or hardware may malfunction due to various reasons, such as a corrupted update, a faulty connection, or a damaged component.
This may affect the audio system of the car, including the turn signal sound.
#2. Firmware bug
Tesla cars receive regular software updates that add new features or fix existing issues. However, some updates may also introduce new bugs or errors that affect the car’s functionality.
For example, some Tesla owners reported that the turn signal no sound issue started after updating to version 2019.32.12.2 or version 2022.24.5.
#3. Disconnected cable
The turn signal sound is generated by the Pedestrian Warning System (PWS), which is a speaker located at the rear of the car. The PWS is connected to the car’s main computer by a cable that runs under the trunk floor.
If this cable is loose or disconnected, the PWS may not work properly and the turn signal sound may not be heard.
#4. Broken rear speaker
The PWS speaker may also be damaged or broken due to various factors, such as water, dirt, or physical impact. This may prevent the speaker from producing any sound, including the turn signal sound.
How To Fix Tesla Turn Signal No Sound Issue?
#1. Reboot the car
The first and simplest solution is to reboot the car’s computer by pressing and holding both scroll wheels on the steering wheel for about 10 seconds, until the touchscreen goes black and the Tesla logo appears.
This may clear any temporary glitches or errors that affect the audio system.
#2. Update the software
The next solution is to check if there is a new software update available for the car, and install it if possible. This may fix any bugs or issues that were introduced by a previous update.
To check for updates, go to the Software tab on the touchscreen and tap on Check for Updates. If there is an update available, follow the instructions to download and install it.
#3. Connect the cable
The third solution is to check if the PWS cable is properly connected to the car’s computer. To do this, you need to access the trunk of the car and remove the floor mat and the plastic cover.
You should see a black cable with a white connector that runs from the rear speaker to the front of the car. Make sure that the connector is firmly plugged into the socket, and that the cable is not damaged or cut.
#4. Change the rear speaker
The fourth solution is to replace the PWS speaker with a new one, if it is broken or damaged. This may require some technical skills and tools, and you may want to consult a professional service center for this.
Alternatively, you can buy a replacement speaker online and follow the instructions to install it yourself.
#5. Unpair phone and pair it again
Sometimes, the Bluetooth connection between the phone and the car may interfere with the audio system and cause the turn signal sound to disappear.
To fix this, you can unpair your phone from the car and pair it again. To do this, go to the Bluetooth tab on the touchscreen and tap on the phone icon.
Then, select Forget Device and confirm. Next, go to the Bluetooth settings on your phone and forget the car. Finally, pair the phone and the car again by following the instructions on the screen.
#6. Unmute the adudio and check the volume
Another possible cause of the turn signal no sound problem is that the audio system is muted or the volume is too low.
To check this, you can press the volume button on the steering wheel or the touchscreen and make sure that the audio is not muted and the volume is at a reasonable level.
You can also adjust the volume of the turn signal sound by going to the Sound tab on the touchscreen and moving the slider for Turn Signal Volume.
#7. Check the speakers and amplifier
If none of the above solutions work, the problem may be related to the speakers or the amplifier of the car.
The speakers may be blown or the amplifier may be faulty, which may prevent the turn signal sound from being heard.
To check this, you can listen to the sound quality of the music or other audio sources and see if there is any distortion or crackling.
You can also inspect the speakers and the amplifier for any visible damage or signs of overheating.
If you find any issues with the speakers or the amplifier, you may need to replace them or visit a service center.
Conclusion
The turn signal no sound problem is a common issue that affects some Tesla cars, and it can be caused by various factors, such as a system fault, a firmware bug, a disconnected cable, or a broken rear speaker.
There are also several possible solutions for this problem, such as rebooting the car, updating the software, connecting the cable, or changing the rear speaker.
However, these are not guaranteed to work, and you should always contact Tesla support or visit a service center if the problem persists or worsens.
